Our key focus for the GT-1000? 11 shoe was to make it softer and smoother. Designed for an active lifestyle, this shoe is functional for running or wearing to the gym. FLYTEFOAM? cushioning in the midsole is tuned with a lower density than the previous version. Teamed with GEL? technology, this combination creates softer landings and smoother transitions. LITETRUSS? technology is placed on the midsole??s inside angle to reduce pronation. It helps produce a more supportive stride while keeping overpronation at bay.
